rename BOTTLE ANDTHE LIKE.

Application filed March 21, 1927. Serial No. 177,035.

This invention relates particularly to in fants nursing bottles and the a like and ure been successful, none have provided anentirely satisfactory solution of the problem.

A further object of the invention is to provide a nursing bottle nipple means forming an integral and component part thereof for facilitating the application of the nipple to and its removalfrom the bottle neck. Such a means is particularly desirable in modern nipples or teats oftheto the bottle and present a comparatively smooth 25 hand type which adhere tenaciously exterior which is extremely grasp. t v;

. A further object of the invention is to provide a nursing bottle having new and improved means for preventing it fromrolling when placed on its side.

Other-objects are to provide a nursing bottle which owing to its peculiar shape can bethoroughly cleansed with' comparative ease, and which canbe manufactured at reasonable cost.

difficult to To this end. my invention consistsofthe construction. and arrangement of the parts 40 hereinafter described and illustrated and pointed out in the claim.

In the. accompanying drawings in which similar reference characters indicate the same parts:

Figure 1 is a side elevation of a nursing bottle constructed according to my inven tion;

Figure 2 is a Figure 3is a sectional view taken on line 3-3 Figure 1; and i i Figure 4: is adetail elevationofthe nipple partly in section. i Referring to these drawings which illustrate the preferred embodiment of my intherefor, and has for its having fragmentary part elevation andpart sectional view of the bottle neck' with the nipple or teat mounted thereon;

vention the bottle proper is indicated at 2 and the nipple at 3.

The body of the bottle is preferably of round cross-section, as indicated in full lines in. Figure 3,-or elliptical, as indicated in dotted lines in the same figure, and is provided witha that external bottom surfaoe 4 to perm t lt-to be placed in upright position, as indicatedin Figure 1, the external surface 5 of the side wall being extended downwardly tothe bottom surface at right angles thereto so that a wide bearing area equal to the full'crosssection of the bottle is provided.

To facilitate the cleansing of the bottle its entire internal surface area is free from corners, ridges or obstructions of any kind.

,To this end the internal surface 6 of the side wall extendsparallel to the external surface thereof from the bottle neck to a point a short distance from its bottom, from which point it curves inwardly to form a concavity 7 constituting an internal bottom. .Theinterior of thebottle thus shaped is of a deep bowl-like formation, the concaved bottom merging with the elongated sides and coacting therewith in providing an unbroken internal surface. This construction and arrangement facilitates cleansing, permits the bottle to be placed on its end in an upright position for filling or any other urpose,and locates sufficient weight in its ottom end to reduce to a minimum the danger of the bottle falling over when in such posi tion.

In order to provide means for preventing the bottle .fromrolling when placed on its sidethe body is provided with external longitudinal ribs 8 which project outwardly a sufficient distance to enable them to function as stops adapted to limit a rollingmovement. If the bottle is ofcircular cross-section it is preferably provided with three ribs arranged equi-distantly apart, as indicated in Figure 3. If, on the other hand, the bottle is of elliptical cross-section, two ribs are preferable. Although an elliptical. bottle has not so much tendency to roll asthe circular type it will roll under certain condi' tionsencountered in actual use, and the pro: vision of the ribsas suggested willbe found to, be of distinct advantage in maintaining the bottle in the desired location. The ribs should be so shaped that they will be free from sharp corners or edges. In the embodiment illustrated they are rounded in cross-section and their extreme ends slope gently towards the external surface of the bottle as indicated at 8. l

The upper portion of the bottle is curved inwardly at 9 on a wideradius and termi-' natcs in a comparatively short neck 10 having an orifice or mouth 12 over which the rubber nipple is positioned.

Heretofore the nipple has been the source of constant trouble owing to its tendency to come off when in use, or to become so displaced as to cause leakage, and many attempts have been made to provide a solution of the problem. a To my knowledge, however,

5 none have proved entirelyvsatisfactor and 'much difliculty is still being experlenced with the various types of nipples now in use.

' The present invention seeks to overcome the problem by so constructing the bottle neck and-the nipple that one will interlock with V the other in such a manner that the possibility of the nipple becoming accidentally dislodged or displaced is positively prevented. In fact with the construction and arrangement of the parts hereinafter described it is impossible to pull the nipple off the bottle if it is grasped at its free end. The preferred embodiment for securing the fore going desideratum consists of a pair of vertically spaced external collars 14 and 15, 1espcctively, formed integrally with the bottle neck and encircling the same at the mouth thereof, and a pair of corresponding-1y spaced internal continuous beads 16 and 17 formed integrally with a skirt or band 18 on the nipple. This skirt or band consists of a comparatively thin elastic sleevelike extension joined to the bottom edge of and being of smaller diameter than the breast or shoulder portion 19 of the nipple and adapted to 'bestretched over the bottle neck, the band, when in position, snugly conforming to the irregular shape presented by the collars and extending downwardly for a short distance below the same. In order to obtain the positive interlocking relationship hereinbefore referred to, the underside of eachcollar is recessed as at 20 in hooked form,and the dimensions and relative spacing of the beads onthe nipple are such that when in position on the bottle the beads snugly'fit within the recesses. It is obvious from this construction and arrangement of parts that any direct pull on the nipple away from the bottle .will simply cause the nipple to grip the bottle more tightly. The interlocking relaure2 and it will be noted that owing to a the inherent elasticity of theband and the 30. breast or shoulder portion the nipple snugly tionship is clearly shown lnsection in Figadheres to the rounded external surfaces of the collars indicated'at 14 and,15' respectively so that a snubbing action at these points is obtained which further assists in preventing dislodgment of the beads :fr m

bottle neck to form a flared mouth. The

lower collar 15 does not project outwardly as far as the top collar, nor is its recess as deep, and its external surface is inclined upwardly and inwardly to the top recess as indicated at 21; The lower collar consequently tapers upwardly to the top collar in trustro-conical form so that if the lower nipple head should become suliiciently displaced to slip over the lower collar it'will slide along the inclined face 21 into the top recess. The beads are of substantially halfroundcross-section and are respectively located at the junction oithetop ed e of the band and the bottom edge of the least or shoulder portion of the nipple 'and at a point ashort distance below the same on the inner face of the band. r

In view of the factthat the collars project beyond the normal exterior of the neck and that the nipple positively interlocks therewith it is desirable to provide means for facilitating the application of the nipple and its removal from the bottle. To this end the band has integrally'formed therewith downwardly extending lips 22 and23 constituting fingerholds which may be grasped in the applying and removing operations. These lips are located diametrically opposite one another and terminate in thickened edges 24.

In applying a nipple or teat constructed according to my invention one of the lips is clamped against the bottle neck With-the forefinger of one hand while the band is ,distended sutliciently, by grasping the other lip with the other handflmtil it can be pulled over the. collars to beads lie snugly within ,the recesses. In the removal operation it is only-necessary to grasp either one of the lips and peel it backward until the beads clear the collars.

Although this inventionis primarily .designed for use in connection with nursing bottles and the like it is to, understood that it may be embodied in other receptacles of like nature without departing from the spirit of the invention.

In certain types of bottles detachable rubber valves are titted over valvular openings in the bottles at or adjacent'to their bottom ends and it is obvious that the applicationof the interlocking feature andthe fingerholds thereto is within the scope of the present invention.

The nursing bottle nipple per se is not claimed herein as the same forms the subject be, distinct-1y its underside, and a nipple or teat fitted over the said mouth and having a breast portion and a sleeve-like extension constituting a band adapted to encircle the bottle neck at and below the said collar and'bei-ng of smaller diameter than the breast portion and having an inwardly projecting bead extending into the recess in the collar and interlocking therewith, said head being inwardly removed from the bottom edge of the band, and a tab-like fingerhold constituted byan 7 integral portion of the band extended down- RALPH G.
